Brief summary

The purpose of this pragmatic interventional study is to evaluate whether a protocol-based management of antithrombotic drugs can reduce a composite of perioperative outcomes in patients with chronic antithrombotic therapy before surgery.

Detailed description

Aging population and chronic medical disease make the management of surgical patients more complex. About one tenth of patients scheduled for surgery are taking antithrombotic medications. Coagulation disturbance induced by these medications may increase the risk of bleeding, whereas withholding these medications may increase the risk of thrombotic events. It is a dilemma when managing these patients. The guidelines and expert consensus published by multiple disciplinary teams constitute the perioperative antithrombotic management protocols. However, the effects of perioperative antithrombotic management guided by these guidelines or expert consensus are seldom reported. The investigators hypothesize that a protocol-based perioperative antithrombotic management can benefit patients with chronic antithrombotic therapy before surgery.

Patients who are scheduled to undergo intra-abdominal surgery (including general and urologic surgery). * 4\. Patients who sign written informed consents.

Exclusion criteria

* 1\. Refuse to participate. * 2\. Emergency surgery. * 3\. Unable to complete the preoperative assessment and follow-up plan. * 4\. Other reasons that are considered unsuitable for study participation by the investigators or the attending doctors.

Design outcomes

Primary

MeasureTime frameDescription
Incidence of a composite outcome including major bleeding and major adverse cardiovascular or cerebrovascular eventsUp to 30 days after surgeryMajor bleeding indicates bleeding of type 2 or higher on the BARC (Bleeding Academic Research Consortium) criteria. Major adverse cardiovascular or cerebrovascular events indicate acute coronary syndrome, acute myocardium infarction, ischemic stroke/transient ischemic attack, systemic arterial embolism, pulmonary embolism, or all-cause death.

Secondary

MeasureTime frameDescription
All-cause mortality rate within 30 days after surgeryUp to 30 days after surgeryAll-cause mortality rate within 30 days after surgery
Incidence of other postoperative complicationsUp to 30 days after surgeryOther postoperative complications indicate any newly occurred medical events that are harmful to patients' recovery and required therapeutic intervention, except major bleeding and major adverse cardiovascular or cerebrovascular events.
The length of hospital stayUp to 30 days after surgeryThe length of hospital stay from admission to discharge
